In this cohort study of 253 patients with knee osteoarthritis, researchers found that platelet concentration positively correlated with clinical improvements in KOOS and IKDC scores over a 12-month follow-up. The high-platelet group (> 1,200,000 platelets/mL) demonstrated a significantly lower reintervention rate of 3.3% compared to 15.0% in the low-platelet group (< 800,000 platelets/mL) at the one-year mark.
